Contradiction with John 7:4
Jesus' brothers suggest He should openly show His works to the world, while in Luke 5:15, Jesus tries to manage the spreading of His fame.
John 7:4: For [there is] no man [that] doeth any thing in secret, and he himself seeketh to be known openly. If thou do these things, shew thyself to the world.
